An auxiliary clamping tool for chassis welding

Abstract

This utility model provides an auxiliary clamping tool for vehicle frame welding, relating to the field of vehicle frame welding clamping technology. It includes: a fixed base plate; fixing grooves at both ends of the fixed base plate; and a supporting frame slidably mounted on the upper end of the fixed base plate. Two electric rods push two clamping plates in opposite directions to fix and clamp the left and right ends of the vehicle frame, while four limiting plates press the frame to prevent it from warping or bouncing due to vibrations during processing. Four positioning blocks then restrict the four supporting legs at the lower end of the frame. This multi-layered clamping constraint prevents displacement even with frequent contact during processing, completely avoiding frame displacement due to external forces. This facilitates precise processing of the frame and solves the problem that when a wide vehicle frame requires processing, it needs to be securely placed on a frame for clamping; otherwise, frequent contact during processing can cause displacement, hindering precise processing.

Description

Technical Field

[0001] This utility model relates to the field of vehicle frame welding clamping technology, and in particular to an auxiliary clamping tool for vehicle frame welding. Background Technology

[0002] In modern industrial production, chassis welding is a crucial step in vehicle manufacturing, and its welding quality directly affects the overall performance and safety of the vehicle. Currently, the auxiliary clamping tools used in chassis welding generally suffer from problems such as unreasonable structural design, difficulty in guaranteeing clamping accuracy, and poor versatility. Some clamping tools cannot achieve rapid and stable positioning and clamping when faced with chassis components of different specifications and shapes, leading to easy displacement of chassis components during welding. This not only reduces welding efficiency but may also affect the overall strength and stability of the chassis due to welding position deviations. Furthermore, traditional clamping tools are prone to wear after prolonged use, further affecting clamping effectiveness and increasing equipment maintenance costs and production risks. Therefore, there is an urgent need to develop an auxiliary clamping tool for chassis welding that can overcome the above-mentioned defects and possess characteristics such as high efficiency, precision, and versatility to meet the growing demands of industrial production.

[0003] During the use of clamping tools, since the frame is relatively wide and needs to be processed, the frame needs to be securely placed on the frame and clamped. Otherwise, the frame will be frequently touched during processing and will shift, making it impossible for workers to process accurately. Utility Model Content

[0004] This utility model relates to an auxiliary clamping tool for chassis welding. When the chassis is laid flat on a support frame for processing, two electric rods push two clamping plates in opposite directions to fix and clamp the left and right ends of the chassis. Four limiting plates press the chassis to prevent it from tilting or bouncing due to vibration during processing. Then, four positioning blocks restrict the four support legs at the lower end of the chassis. In this way, the chassis is subject to multiple clamping restrictions, and the chassis will not shift even if it is frequently touched during processing. This completely avoids the chassis shifting due to external forces, making it convenient for workers to process the chassis accurately.

[0005] In a first aspect, this utility model provides an auxiliary clamping tool for vehicle frame welding, specifically comprising: a fixed base plate; fixed grooves respectively formed at both ends of the fixed base plate; a supporting frame slidably mounted at the upper end of the top of the fixed base plate, and arc-shaped grooves respectively formed at the upper ends of both ends of the supporting frame; symmetrical clamping plates slidably mounted in the middle of the supporting frame; slots respectively formed at both ends of the upper ends of the two clamping plates, and slots formed at the bottom of the slots of the clamping plates;

[0006] Limiting plates are slidably installed at the slots of the two clamping plates, and through rod holes are provided on the limiting plates. Pull rings are fixedly installed on the outer sidewalls of the four limiting plates. Track grooves are provided on the two sidewalls of the four limiting plates. Through rods are inserted into the rod holes of the four limiting plates. Limiting plates are fixedly installed at the lower ends of the four limiting plates. Symmetrical positioning blocks are slidably installed on the sidewalls of the two clamping plates facing each other, and parallel sliders are fixedly installed on the sidewalls of the positioning blocks.

[0007] Each of the four positioning blocks has a stabilizing disc fixedly installed on its side wall, and a ring of through bolts is inserted at the edge of the stabilizing disc; a bearing ring is fixedly installed in the middle of each of the four stabilizing discs, and a threaded rod is fixedly installed in the inner ring of the bearing ring; a threaded cylinder is rotatably fitted on the opposite end of the two threaded rods on the left, and a threaded cylinder is rotatably fitted on the opposite end of the two threaded rods on the right.

[0008] Furthermore, a synchronous hydraulic cylinder is fixedly installed in each of the two fixing slots of the fixed base plate, and a connecting block is fixedly installed at the upper end of the synchronous hydraulic cylinder. Vertical anti-detachment rods are fixedly installed at the four corners of the fixed base plate.

[0009] Furthermore, the two ends of the support frame are respectively provided with symmetrical anti-detachment holes, and the inner sidewalls of the two ends of the support frame are provided with parallel guide grooves.

[0010] Furthermore, a vehicle frame is placed in the middle of the upper end of the support frame, and electric poles are fixedly installed at the arc-shaped grooves at both ends of the support frame.

[0011] Furthermore, parallel sliding grooves are respectively opened on the side walls of the two clamping plates facing each other, symmetrical guide blocks are respectively fixedly installed on the side walls of the two clamping plates, and symmetrical track blocks are fixedly installed on the inner side walls of the grooves of the two clamping plates.

[0012] This utility model provides an auxiliary clamping tool for vehicle frame welding, which has the following advantages:

[0013] In this utility model, when the clamping device is in use, the frame is laid flat on the support frame for processing. Two electric rods push two clamping plates in opposite directions to fix and clamp the left and right ends of the frame. Four limiting plates press the frame to prevent it from tilting or bouncing due to processing vibration. Then, four positioning blocks restrict the four support legs at the lower end of the frame. In this way, the frame is subject to multiple clamping restrictions. Even if the frame is frequently touched during processing, it will not shift. This completely avoids the frame shifting due to external forces, making it convenient for workers to process the frame accurately.

[0014] Two synchronous hydraulic cylinders can be used to adjust the support frame up and down. When the support frame is adjusted to a suitable height, it is convenient for the frame to be disassembled and assembled. At this time, the height of the support frame and the frame is adjusted to a suitable height to facilitate the worker's processing. This avoids the worker working at an unreasonable height that is too high or too low. The appropriate height allows the worker to operate tools and load and unload parts more smoothly, reducing redundancy and pauses in movements, improving the overall work rhythm, avoiding bad postures such as bending over, looking up, or standing on tiptoe for a long time, reducing muscle fatigue and strain in the waist, neck, shoulders, and legs, and reducing the physical burden on the worker.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 4 :

[0025] This utility model discloses an auxiliary clamping tool for vehicle frame welding, comprising: a fixed base plate 1; fixed grooves are respectively formed at both ends of the fixed base plate 1; a supporting frame 2 is slidably installed at the upper end of the top of the fixed base plate 1, and arc-shaped grooves are respectively formed at the upper ends of both ends of the supporting frame 2; symmetrical clamping plates 3 are slidably installed in the middle of the supporting frame 2; slots are respectively formed at both ends of the upper ends of the two clamping plates 3, and slots are formed at the bottom of the slots of the clamping plates 3; symmetrical positioning blocks 4 are slidably installed on the side walls of the two clamping plates 3 facing each other, and the side walls of the positioning blocks 4 are fixed. Parallel sliders 401 are fixedly installed; sliders 401 are slidably installed in grooves 301. When the positioning block 4 slides back and forth, sliders 401 are restricted by grooves 301, and the positioning block 4 can only slide back and forth, preventing the positioning block 4 from shifting or tilting when sliding back and forth, so that the side wall of the positioning block 4 cannot be stably attached to the support leg of the frame 203. A stabilizing plate 402 is fixedly installed on the side wall of each of the four positioning blocks 4, and a ring of through bolts is inserted at the edge of the stabilizing plate 402; the bolts on the stabilizing plate 402 are rotated and inserted into the positioning block 4, so that the stabilizing plate 402 is fixedly attached to the support leg of the frame 203. 2. The bearing ring 403 is fixedly restrained on its outer ring, and will not move when touched. The bearing ring 403 is fixedly installed in the middle of the four stabilizing discs 402, and the inner ring of the bearing ring 403 is fixedly installed with threaded rods 404. Threaded cylinders 405 are rotatably fitted onto the opposite ends of the two threaded rods 404 on the left end, and threaded cylinders 405 are rotatably fitted onto the opposite ends of the two threaded rods 404 on the right end. Anti-slip sleeves are fixedly installed in the middle of the outer wall of the threaded cylinders 405. When the anti-slip sleeves on the threaded cylinders 405 are grasped and rotated clockwise, the threaded cylinders 405 move back and forth. The threaded rods 404 at both ends will move in opposite directions, and at the same time, the two threaded rods 404 will also push the two positioning blocks 4 in opposite directions. The side walls of the two positioning blocks 4 will be firmly attached to the support legs of the frame 203, blocking and restricting the support legs on the frame 203. When the frame 203 is touched, it cannot move back and forth, which makes it convenient to process the frame 203. Conversely, if you grasp the anti-slip sleeve on the threaded cylinder 405 and rotate it counterclockwise, the threaded rods 404 at both ends of the threaded cylinder 405 will pull the two positioning blocks 4 in opposite directions. At this time, the frame 203 can move back and forth, which is convenient for installation or removal.

[0026] The fixed base plate 1 has two fixed slots on which synchronous hydraulic cylinders 101 are fixedly installed. The upper end of the synchronous hydraulic cylinder 101 is fixedly installed with a connecting block 102. The two connecting blocks 102 are fixedly connected to the two sides of the support frame 2. The two synchronous hydraulic cylinders 101 can move the two connecting blocks 102 up and down at the same time. At this time, the support frame 2 will also move up and down to adjust its height, which is convenient for placing the frame 203 for processing, or removing the frame 203 from the support frame 2. At the same time, the height of the support frame 2 and the frame 203 is adjusted to a suitable height for workers to process. The four corners of the fixed base plate 1 are fixedly installed with vertically upward anti-detachment rods 103. The anti-detachment rods 103 slide through the anti-detachment holes 201. When the support frame 2 slides up and down, the anti-detachment holes 201 on the support frame 2 are restricted by the anti-detachment rods 103. The support frame 2 can only slide up and down, preventing the support frame 2 from shifting or tilting when sliding up and down.

[0027] The support frame 2 has symmetrical anti-detachment holes 201 at both ends, and parallel guide grooves 202 on the inner sidewalls of both ends. A frame 203 is placed in the middle of the upper part of the support frame 2. The frame 203 is placed flat on the support frame 2. Two electric rods 204 are used to push two clamping plates 3 in opposite directions, temporarily fixing the two ends of the frame 203 with one end of the clamping plates 3. This prevents movement when the frame 203 is touched during processing, thus ensuring precise machining of the frame 203. The front and rear support legs at the lower end of the frame 203 are in contact with the sidewalls of the front and rear positioning blocks 4. The four positioning blocks 4 are respectively positioned on the four... Electric rods 204 are fixedly installed at the arc-shaped grooves at both ends of the supporting frame 2, with their inner sidewalls abutting against each other. The opposing ends of the two electric rods 204 are fixedly connected to two clamping plates 3. Parallel sliding grooves 301 are respectively opened on the opposing sidewalls of the two clamping plates 3. Symmetrical guide blocks 302 are fixedly installed on the sidewalls at both ends of the two clamping plates 3. The guide blocks 302 are slidably installed in the guide grooves 202. When the clamping plates 3 slide left and right, the guide blocks 302 are restricted by the guide grooves 202, allowing the clamping plates 3 to slide only left and right, preventing them from shifting or tilting. Symmetrical track blocks 303 are fixedly installed on the inner sidewalls of the grooves of the two clamping plates 3, restricting the track on the plates 304. The track groove 305 is slidably mounted on the track block 303. When the limiting plate 304 slides left and right, the track groove 305 on the limiting plate 304 is restricted by the track block 303, and the limiting plate 304 can only slide left and right, preventing the limiting plate 304 from shifting or tilting when sliding left and right. The limiting plates 304 are slidably mounted at the slots of the two clamping plates 3, and the limiting plates 304 have through rod holes. Pull rings are fixedly mounted on the outer side walls of the four limiting plates 304, and it is convenient to move them by grabbing the pull rings on the limiting plates 304. Track grooves 305 are opened on the two side walls of the four limiting plates 304. The track grooves 305 on the limiting plates 304 are restricted by the track block 303 and cannot move up and down. The rod holes of the four limiting plates 304 are located at... Insert rods 306 are inserted through the limiting plates 304 and inserted into the slots of the clamping plates 3. Limiting plates 307 are fixedly installed at the lower ends of the four limiting plates 304. When the limiting plates 304 at the left and right ends are pushed towards each other, when the side wall of the limiting plate 307 is in contact with the side wall of the clamping plate 3, the rod holes on the limiting plates 304 are vertically aligned with the slots at the bottom of the clamping plates 3. Then, insert rods 306 through the limiting plates 304 and insert them into the slots of the clamping plates 3 to temporarily fix and restrict the limiting plates 304. At this time, the bottom of the opposite end of the limiting plates 304 at the left and right ends will press down on the edge of the frame 203 to restrict the frame 203. When the frame 203 is touched, it cannot move upward.

[0028] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, a stabilizing plate 402 is fixedly installed on the side wall of each of the four positioning blocks 4, and a ring of through bolts is inserted at the edge of the stabilizing plate 402. The bolts on the stabilizing plate 402 are removed, and then the stabilizing plate 402 is fixedly glued to the positioning block 4 to stabilize and restrict the stabilizing plate 402. In this way, the stabilizing plate 402 and the bearing ring 403 will not fall off when touched, avoiding the bolts from loosening and failing to fix the stabilizing plate 402 after long-term use, and also saving on parts costs.

[0029] The working principle of this embodiment is as follows: During use, the frame 203 is placed flat on the support frame 2. First, two electric rods 204 are used to push the two clamping plates 3 in opposite directions, temporarily fixing and clamping the two ends of the frame 203 with one end of each clamping plate 3. The frame 203 will not move when touched during processing. Next, the limiting plates 304 at both ends are pushed in opposite directions. When the side wall of the limiting plate 307 is in contact with the side wall of the clamping plate 3, the rod holes on the limiting plate 304 and the slots at the bottom of the clamping plate 3 overlap vertically. Then, the insertion rod 306 is inserted through the limiting plate 304 into the slot of the clamping plate 3, temporarily fixing and restricting the limiting plate 304. At this time, the bottom of the opposite ends of the limiting plates 304 at both ends will press down on the edge of the frame 203, pressing down and restricting the frame 203. When the frame 203 is subjected to... When touched, it cannot move upwards. Then, grasp the anti-slip sleeve on the threaded cylinder 405 and rotate it clockwise. At this time, the threaded rods 404 at both ends of the threaded cylinder 405 will move in opposite directions. At the same time, the two threaded rods 404 will also push the two positioning blocks 4 in opposite directions. The side walls of the two positioning blocks 4 are used to smoothly and tightly adhere to the support legs of the frame 203, blocking and restricting the support legs on the frame 203. When the frame 203 is touched, it cannot move forward or backward, thus facilitating the precise machining of the frame 203. Two synchronous hydraulic cylinders 101 can move the two connecting blocks 102 up and down at the same time. At this time, the support frame 2 will also move up and down to adjust the height, making it convenient to place the frame 203 for machining, or to remove the frame 203 from the support frame 2. At the same time, the height of the support frame 2 and the frame 203 is adjusted to a suitable height for workers to process.
